Letters Patent No. 93,803, dated August 17, 18.69.

IMPROVEMENT MACHINE FIOR CUTTING LEATHER INTO ROUND BANDS.

The Schedulereferred to in these Letters Patent and making part cf theysame.

Tcall whom it may concern.- 1 Be it known that I, CHRISTOPHER G.BURNHAM, 3f East-Hartford, in the county of Hartford, and State )fConnecticut, have inventedv a new and useful Improvenient in Devices forCutting Leather into Round Bands; and I declare the-following. to be afulland exact description thereof, reference being 'had to theaccompanyingfdrawings, and to the letters of refernee thereon,formingva. part of this specification.

Figure' 1 is a side elevation, in section, of my device.

The letter a designates the frame of the machine, 3f which a is thebase, and a, the single uplight upon t. This frame is made ofcast-metal, preferably of iron or brass.

The letter' b designates a movable upright, adjustxble backward andibi-ward in the rslot c, and fastenedl when properly adj usted by thenut (1.

Upon the side of the movable upright bv are two iuts or shoulders, oneofwhich, C, is seen in the drawngs, situated upon either side ofthe slotc.

In the ends of .these shoulders are adj usting-screws F, which bear downagainst the base ofthe frame, and )y means of which the top of themovable upright can Je canted somewhat backward or forward, as desired.

It should be stated just here, that the drawing is bout the sizev of aworking machine, and that the breadth of the basea thing not to bedetermined by i. view of the drawing-is one and three-fourths inches.lhe base is to be screwed to a table.

Into the upright a is screwed the cutter: h, which is round upon theoutside, and has a4 round hole through zhe centre; in fact, it closelyresembles the hollow cutter of a belt-punch. y

Different sizes of these cutters can be used to cut .liierent sizes ofbands.

The letter t' designates a knife, hung in a slot in the top of theupright a, and tightened in its place by the thumb-screw k. -The oice ofthis knife is to divide the waste leather upon each side, asl the striplis pulled through the cutter.

In the top of themovable upright bis a square hole, m, considerablylarger than any strip `of leather which `not united to each other, andwill permit strips of 'different size to pass through.

vTheletter o designates a strip of leather,'wl1i :h is being drawnthrough the device.

It is square at o1, but when it comes through at o2 it is round, thesurplus leather' having been stripped o' bythel cutter h. and the knifez', and taking the direction o.

To start a strip through this device, it must first be pointed, anddrawn through till it can be seized at o2, when the pulling can becontinued by manual or machine power.

'The product is used-for sewing-machine belts, whip- 1ashes,'and` thelike.

I claim as my invention- 1. The combination of the springs n vn n n, andthe cutter h.

2. The combination of the springs n. n 'n 1l., the cutter h, and theknife i, the Whole being constructed and arranged as described, for thepurpose set forth.
